OIL-WELL- -DRILLING RIG.

Applicationfiled October 21, 1927. Serial No. 227,750.

This inventionrelates to new and useful improvements in oil well drilling rigs and.

I aims to provide aunitary structure for use in performing the various operations incident to the drilling of a well such as the spudding in of the wlelh-the placingof the well casing section, the drilling and bailing of the well.

The invention further aims to" provide a.

well drilling rigwhei'ein the same asa unit may be jacked up and moved from-one well to another within a particular oil field, and that furthermore may be entirely :disassembled for repair, renewal, or transportation or storage purposes.

Further, the location. of the various structural' elements with respect to the rig'frame is such that all lo'ads will be substantially centered with respect to thecomplete unit so thatthere will beno liability whatever of the rig bucking or tilting.

ous operations necessary in the drilling of an oil well may be performed through .the

medium of the single mechanism.

With the foregoing and other objects in view as the nature of the invention will be better understood,- the same comprises-the novel form, combination and arrangement of parts hereinafter more fully descr1bed,- shown in the accompanying drawings and claimed. In the accompanying drawings wherein like references lndicate corresponding parts throughout the several views:

Figure 121s a fragmentary perspective of a circular friction band that constitutes an es- -.95

sential element of the clutch mechanism, and

associated with: the power shaft bull wheel; Figure 13 is an enlarged" fragmentary sec- .Fi'gure 14; an enlarged fragmentary section through the upper .end of the rig mast for more clearly disclosing one of the block d and tackle cable guide pulley units, and j Figure 15 is a front elevation of the upper end of the mast for more clearly disclosing the positioning of these cableguide pulley units with respect to the rig mast- Now having particular reference to the drawings, mynovel rig consistsof a horizontal bed frame consisting of outer longitudinally extending frame bars 5-5 and a pair of 1 U v Figure 5 1s a: fragmentary elevation ofthe side of the rig opposite to that"disclosed in Figures-1', 2 and 3 formore cle'arly disclosspaced parallel central longitudinally extending frame bars 66. Extending transversely beneath these bars 5 and 66 and at predetermined spaced relation with each other are transversely extending bars 7 that are of course rigidly secured to the longitudinally extending bars and serve to support the same in'Figures l, 2 and 3.

above the ground surface as clearly disclosed Furthermore, this bed frame consists of a transversely extending bar 8 arranged across the longitudinal bars 5 and 6, and bolted thereto, this barIS being dlsposed at ,a point adjacent one end of the bed frame as alsoldisclosed in Figures 1, 2 and 3 as Well as in Figures 5and 8. At the outer sides of the central longitudinally extending frame bars 6-6 the front side of the transverse bar 8 is equipped with hinge sections 99, wh1le normally supported'upon this transverse bar 8 is the lower end of an upwardly and slightly inclined mast'structure 10 that includes generally side bars 11-11 of interconnected secttional formation the lower ends of the bottom v sections being formed with forwardly extending toes.1212 for pivotal attachment to the hinge member's 99 of the transverse bed frame bar 8. for the obvious purpose of permitting the mast to be swung downwardly Whenever desired. r x

The side bars 11 11 of the 'mast structure '10 converge slightly inwardly toward theirv upper ends, while said side bars are braced at predetermined spaced points by horizontal strut bars 13 and diagonally extending struts 14. Adjacent the lower end of this mast 12 two adjacent horizontal struts 13 are interconnected by a pair of spaced guide members 1515 as clearly disclosed in Figure 7. By a consideration of this view it will be noted that the diagonal struts between the two horizontal struts carrying the vertical guides 1515 are so arranged as not to cross the space between said Vertical guides, the purpose of which is to permit the forward end of the walking extended therefrom, the ends of these guy.

wires being obviously anchored to the ground and serving to prevent rocking of the mast during operation of the rig.

i Extending transversely between thesidemembers 11-11 of the mast structure 10 adj a cent the upper. end there is a wall 13, while extending vertically from this wall 18 intermediate the ends thereof is a'pair of spaced parallel arms 1919, upon the upper end of which is mounted for rotation a cable guide pulley 20. Beneath this pulley 20 thereis arranged between the arms 19-19 a small counter said post. However, in the" event woaeev cable guide pulley: 21. Beneath the outer sides of the arms 19-49 and the upper ends of the side members-of the mast structure are insert'brace's 2222, while arranged within the spaces between the side members of the mast 7 structure and the arms 19-19 are sheave carriers. designated generally by the reference characters 23-23. Each sheave carrier con sists of three spaced parallel metallic plates 2% between the upper ends of which are cable. sheaves designated in each instance by the reference characters 2525. These sheave carriers are pivoted'within the mentioned spaces; of the mast structure adjacent their'forward edges bya cross pin 26. Therear edges of the plates comprising'these sheave carriers are formed adjacentthelr upper ends with rearwardly extending somewhat arcuate shaped tongues 27 within each of which is an arcuate slot 28 through which a pin 29 extended trans versely of the mast structure is arranged. Obviously, this pin and slot arrangement regulates the degree of swinging movement of the sheave carriers with respect to the mast structure, as clearly disclosed in Figure 14.

Secured at theirf lower ends to the bed frame of the rigtdirectly in'back of the trans versely extending mast supporting bar 8 is a double standard Samson post 30, the standards of which are in spaced parallelrelation and that are braced adj acenttheiriupper ends by downwardly and rearwardly extending brace rods 31connected at their lower ends- ,to the inner sides of the central longitudinally extending bed frame bars 6-6. F urthermore, the standards of this Samson post are braced to the side members of the mast structure 10 by suitable straps 32. The up per-ends of the standards of this Samson post are equipped with shaft bearings 33 33 for receiving the opposite ends of a rock shaft 34 that is suitably attached to the top surface and intermediate the ends of a walking beam 35. Obviously, by reason ofthis particular character of connection between the walking beam and the Samson post there is provided an underslung connection permitting the walking beam to operate properly under unusual strain. The forward end of the walking beam 35 is equipped for receiving theusual depending temper screw 36 and at its rear end the usual depending shaft pitman 37. Secured at its lower end to the mast supporting bar 8 of the'rig bed frame intermediate the standards of the Samson post 30 is a vertically extending and slightly for wardly projecting post 38, the upper end of which terminates considerably beneath the upper end of the Samson post and that is 5" also braced at its upper end to the Samson 1 1 post as indicated by the reference character 39. The length of this post 38 is such that,

under the normal movement of the walking beam 38the forward end thereof will not en ing posts -'40 suitably braced to the frame and upon the upper end of which is j ournaled a power shaft :41. At. the inner side'of the outermostshaft ,post 40 said shaft 41 has keyed thereto a\be'lt receiving rotary pull wheel 42 over which is to be extended a rearwardly directed endless belt 43 that is invturn trained over a pulley upon the power shaft of a suitable source of supply, not disclosed.

Arranged upon the inner end of this shaft 41 which projects inwardlyof the innermost shaft post 40 is a crank arm 43' equipped at its free endwith a horizontal pin 44 for attachment to the walking beam pitman 37 or for receivinga cable pulley 45, as disclosed in Figures 3 and 1, respectively;

Arranged upon the outer longitudinal frame bar 5 of the bed frame in back of the rotary bull wheel 42 is a vertically extending bracket 46, see Figure 5 to which is pivotally secured a vertically extending lever 47. Arranged for rotation within a'socket formed at th'e'inner side and adjacent the lower end outer end of the shaft and'the vertical lever of this lever 47 is one end of an-inwardly extending transverse shaft 48, the inner end of which is suitably journated upon the upper end of a standard 49 arranged upon the fore- -most central longitudinal bar 6 of the bed frame of the rig as clearly disclosed in the top plan view of Figure 8. The bearing for this end of the shaft is preferably longitudinally and vertically adjustable -so. that the shaft may be properly centered with'respect to the. attaching point between the 47. This shaft 48 has keyed thereto a double cable drum 50 of generally conventional construction and upon which is wound a cable 51, which is adapted to be wound upon and released from the inner drum section, as'in Figure 8. The inner end' ofthis double drum terminates considerably inwardly of the rotary bull wheel 42 for a'purpose presently' to be described.

Adjacent the point of attachment of the outer end of the shaft 48 with respect to the vertical lever 47 saidshaft is equipped with a friction wheel 52 directly in alinement with the bull wheel 42 and adapted to have fricp tional engagement therewith when the lever 42 is swung in a forward direction, with the obvious result that rotation is imparted to the shaft 48 for winding the cable 51 thereon. From the drum 50 this cable 51 extends tion of said shaft 48.

upwardly and is trained over the pulley 21 arranged bei'i'eathythe uppermost pulley 20'of the mast construction 10. Arranged upon the free end of this cable 51 isa conventional bailer bucket 53th,:itds to be raised and lowered into the well by the forced rotation of the drum carrying shaft 48 or the releasing 'of the shaft,respectively; Obviously, the

movement of the friction wheel 52 from the surface of the bullwheel 42 after the bailer has been raised will permit the same to drop into the well under its own weight. -.In order to break the descent of thebailer bucket when the shaft 48 is-released, there is arranged in back of the friction wheel 52 upon the adja-- cent outer longitudinal bed frame bar, a post 54, the edge adjacent the friction wheel 52 being curved and having a braking'face- 55f thereon. Obviously by'moving the lever 47%;

rearwardly. with respect to the bull wheel 42, said friction wheel 52 will be moved against the braking vface 55 for,stopping the rota-,

of the bull wheel and post 54 at opposite sides of the friction wheel 52 is such that the wheel may be maintained out of contact with the post and bull wheel. topermit of the free The relative .position mov'ei'nent of the shaft 48 duringv the dropping of the bailer bucket.

Any means may be .provldedtwhereby the lever 47 may be operated, this means preferably consisting of a bar 56 that extends forwardly and downwardly at the outer side of the bull wheel 42, and that'is pivotally connected at one end to the lever 47 and at its opposite end to a crank 57 upon one end of a transversely extending rock shaft 58. see Figure '5, that is suitably mounted upon the vmast supporting bar 8 and that is equipped at its inner end with ahandle 59 Mounted upon vertical jack posts 61- 61at the rear ends of the outermost longitudinal frame bars 15- 5 are the opposite ends of a trans-- versely extending shaft 62. This shaft 62 is equipped with a relatively large double cable drum 63, the innermost end of which is direetly in back of the center of the-bailer cable drum 50, as clearly disclosed in Figure 8. Wound upon this drum 63 is a cable 64 that extends upwardly from the innermost drum section and that is trained over the upper- 'most pulley 20 of the mast construction 10 from where the same extends downwardly and has attached to its-free end a suitable drilling tool 65. Obviously when the-bailer 53 is being operated. this tool is extended out of the path of movement-of the bailer. and

so held in any suitable manner, and by the same t-okenthe bailer 53 is extended out of osition above the well during the operation of the drill tool 65. I

In spaced relation with the inner end of the drum 63. the shaft 62 has keyed thereto:

a relatively large pullevwheel 66, the-face of which is formed with a pair of circumferential channels, preferably of V-sha'pe in cross section s milar to the channels disclosed in one of the elements shown in F1gure13.

' Arranged upon the inner faceof the rotary bull'wheel 42 and of smaller diameter than the pulley wheel 66 is a ring 67 ofgeneral l.- shape in crosssection' as disclosed in Figures 12 and 13. The vertical wall of this ring is bolted or otherwise rigidly secured to the inner face of the rotating bull wheel 42, while the horizontal wall thereof is formed at equally spaced points with circumferential slots 68 preferably four in number. Arranged for free turningmovement upon the horizontal wall of the ring 67 is a collar 69 that is formed with a pair of circumferentially extending channels 70 of V-shape in cross section, as clearly disclosed in Figure 13. Loosely mounted upon the power shaft ll to which the bull wheel 42 is he ed is the hub 71 of a generally similar whee -like unit 72 that includes a circular rim portion 73' movement within the outer end of cylinders 77 arranged at their outer ends wlthin openings' in the rim 73 of said wheel-like unit 7 2, see Figures 11 and 1?).- Movable through each cylinder 77 and slidable through the outer end wall thereof as well as through the adjacent wall of thecup 76 of the complenientary brake shoe is a pin 79 is'equipped on the outer end'of the pin 78 and is operablewithin the cup 76. This head is adapted to engage within the ad acent slot of the rlng 67 when projected into the position indicated in Figures 11 and 13,

Surrounding each pin 7 8 within its cylinder 77 is an expansible coil spring 80, the purpose g of which is to normally exert an outward pressure against the cup of the respective shoe 7 5 for causing frictional engagement of the same with the horizontal wall of the ring 67 for therebylocking the ring to the/wheelike unit 72 that is connected with thepulley 'collar 69. y

7 The inner end of e'achpin 78 beyond the cylinder 77 carries ahead 81,1while to these various. heads are pivotally connected-the outer ends of radiating arms 82'the inner ends of which are pivotally connected to a clutch throw collar 83 slidable uponthe hub portion 71 of the wheel-like unit 72. ()peratively associated with this collar 83 is the 78. A head oder? upper yoked end of a lever 84 which is pivoted in spaced relation with the inner side of the ad acent power shaft jack-post 40 through the instrumentality of a horizontal bracket 85. Pivoted to the lower end of this lever is an inwardly extending link member 86 that is in turn pivotally connected at its inner end to a bell crank 87 that is pivoted as at 89 to the adjacent central longitudinal frame bar 6. Pivoted to the outer end of the bell crank 87 is the inner-end of a control rod 90 that extends rearwardly of the rig and that is plvoted at its. outerend to the lower end of a hand lever 91 that is pivoted adjacent its lower end to a bracket 92 arranged upon the acent central longitudinal frame bar, see

' Trained. around the pulley Wheel 66 of the drum shaft 62and the collar 69 of the'clutch unit is a pair of endless \I-type belts93-f-93 that obviously work in the circumferential" channels of said wheel and said collar. From a careful consideration of Figure 13 itwill .be readily understood-that the inward movement of the collar 83 will cause the outward movement of the pins'7 8 which will release the pressure-of the heads 79 of said pins from the bottom wallslof the shoe cups "7 6 whereupon thesprings 80 will exert their force to frietionally engage the shoes 7 5 with the horizontal wall of the ring 67, thus providing a friction clutch between 'thebull wheel and said collar 69. As soon as the circumferential slots 68 of said ring 67 move into the path of the head 9 ofsai'd pins, the heads will engage 'Wltlllll said slots for causinga positive lock between the bull'wheel and said collar.

The power rotation of the double cable I drum 63 will cause the winding of the cable 64 thereon with the obvious result of raising the drill tool 65.' As soon as the clutch is released, the tool drops underits own weight which is a generally conventionaldrilling action.

Within the shaft post61 the end of the shaft 62 opposite fromv that equipped with the belt pulley 66 is equipped with a friction wheel 94 over'whichisarranged a metallic brake band 95,"0ne end of which is anchored to the adjacent bed frame 5 as clearly disclosed in Figure l, The opposite end of this band is connected in'a conventional manner toa stub crank shaft 96; the outer end of which is equipped wit-ha 'crank"'97 to which I is pivoted'one end of a rod 98 that extends forwardly and that is operatively connected to the lower end of a throw lever 99 pivotally attached adjacent its lower end with the upper end of a suitable standard 100'that is arranged upon the adjacent outer longitudi nal bed frame bar 5.

Suitably journaled upon the upper ends of short shaft posts 101%101 between the mast construction 10 and the rotary bull wheel 42 is a transverse shaft 102 that is equipped at the inner side of the bull wheel- 42 with a double cable drum 103 upon which is wound a length of cable 104,'which cable extends upwardly and is guided over a small pulley 105 associated with the backside and lower end of the adjacent sheave carrier 24 pivoted within the upper end of the'mast conof the block and tackle arrangement the drill tool and bailer bucket are disposed out of the path of movement'of the block While the pivotal' sheave carriers 24-24:- are swung outwardly so that the block of the block and tackle will be centereddirectly above the well. At the inner end of this drum shaft 102 I the same is equippedwith a sprocket gear 107 over which is trained a rearwardly and upwardly extending sprocket chain '108 and that is'in turn trained over a sprocket gear 109 carried by a clutch collar movable upon the shaft 41 and is complementary to another rigidly mounted clutch collar upon said shaft with the obvious result that when the sliding collar is moved into engagement ,with the rigid collar, rotation will be imparted to the drum 103 for winding the cable thereon for raising theblock 106. The releasing of the collar will permit the block to drop of its own Weight, while the rotation of the drum shaft may be checked during the downward movement of the block by suitable banil brakes designated generally by the reference character 110, the band of which is operable from the adjacent side ofthe machine by a lever 111 that may be maintained in braking position by suitable fastener 112 arranged on the outer side of the adjacent bed frame bar 5. Obviously, after the spudding in operation has been performed, the drill tool cable 64 is attached to the temper screw 36 so that the deep drilling operation may be performed-in a generally conventional manner.

It will thus be seen that I have provided a highly novel, simple and extremely useful Well drilling rig that is well adapted for all though I have herein shown and described the invention as consisting of certain detail structural elements it is nevertheless to be understood that some changes may be made of the appended claims.

Having thus described the invention, What I claim asjnew is 1. In a well drilling rig, a bed frame, a verthefpurposes heretofore designated, andeven therein without affecting the spirit and scope tical mast structure secured at its lower end to the frame, a series of independently operable cable drums disposed upon the frame in back of the mast, cables arranged upon said drums and adapted to be extended through the mast at the upper end thereof, 'a pair of Vertically arranged transversely spaced units pivotally arranged at their lower ends Within the mast, sheaves arranged within the units, the cable from one of the drums adapted to be so guided over the sheaves -as to provide a tackle structure, a pulley block unit arranged upon thevarious runs of the tackle,. and means whereby the various drums may be rotated in a certain direction for winding the cables thereon. i
